The manual operation process is cumbersome, which not only easily contaminates the microfluidic discs, but also reduces the detection efficiency of the instrument. Based on the above problems, although some loading devices for microfluidic discs have emerged, these loading devices can only store a small amount of a single type of reagent disc due to structural limitations, which significantly slows down the detection efficiency.

[0040] Referring to FIG. 1 , an embodiment of the present application provides a detection system, including a loading device 1000 for loading materials. The loading device 1000 includes a storage device 100 and a material taking device 200 disposed on one side of the storage device 100. The storage device 100 is used to temporarily store materials, and the material taking device 200 is used to take materials from the storage device 100 and provide them to downstream detection equipment. Specifically in the following embodiments, the material stored and transported by the loading device 1000 is a disc-shaped microfluidic reagent disk 2000.

[0041] Please refer to Figures 1 to 3. The storage device 100 includes a mounting seat 120, a rotating mechanism 140, a driving mechanism 160 and at least one storage unit 180. The mounting seat 120 is placed on the placement surface to play a role of fixing and supporting. The rotating mechanism 140 is installed on the mounting seat 120, and the rotating mechanism 140 has at least one storage space 140a, and all storage spaces 140a are arranged at intervals along the first direction. The driving mechanism 160 is installed on the mounting seat 120 and is transmission-connected to the rotating mechanism 140. The driving mechanism 160 is used to drive the rotating mechanism 140 to rotate around a rotating shaft 165 extending along the first direction. Each storage unit 180 is detachably limited in the storage space 140a, and at least one storage unit 180 is arranged in each storage space 140a, and each storage unit 180 has a sub-storage space 180a for accommodating materials (as shown in Figure 6).

[0042] Thus, the storage device 100 has one or more storage spaces 140a, and one or more storage units 180 can be arranged in each storage space 140a, and each storage unit 180 can accommodate one or more reagent discs 2000. Therefore, the storage device 100 as a whole can not only store a large number of reagent discs 2000, but also place different types of reagent discs 2000 in different storage units 180, thereby improving the detection efficiency and detection diversity of the detection system provided with the storage device 100. Moreover, the operator can disassemble any storage unit 180 as a whole to conveniently place multiple reagent discs 2000 in batches, thereby facilitating the use of the loading device.

[0043] Specifically, referring to FIG. 1 and FIG. 4 , the mounting seat 120 includes a bottom plate 121 and a mounting seat body 123. The bottom plate 121 is a flat plate structure, and the mounting seat body 123 is a hollow shell structure with one side open. The mounting seat body 123 is covered on one side of the bottom plate 121 in the thickness direction, and the mounting seat body 123 and the bottom plate 121 form a receiving cavity for installing the driving mechanism 160. In the following embodiments, the height direction of the mounting seat 120 is defined as the first direction (i.e., the Z direction in FIG. 1 ), the length direction of the mounting seat 120 is defined as the second direction (i.e., the X direction in FIG. 1 ), and the width direction of the mounting seat 120 is defined as the third direction (i.e., the Y direction in FIG. 1 ).

[0044] The driving mechanism 160 includes a rotating driving member 161, a first driving wheel 162, a first synchronous belt 163, a first driven wheel 164 and a rotating shaft 165. The rotating driving member 161 is installed on a side of the mounting seat body 123 away from the bottom plate 121 and is located on a side of the rotating mechanism 140 in the second direction. The output shaft of the rotating driving member 161 passes through the mounting seat body 123 downward along the first direction and extends into the accommodating cavity. The first driving wheel 162 is fixed to one end of the output shaft of the rotating driving member 161 extending into the accommodating cavity, and the first driving wheel 162 can rotate around the first direction following the output shaft. The first driven wheel 164 is accommodated in the accommodating cavity and is located directly below the rotating mechanism 140. One end of the rotating shaft 165 is inserted into the center hole of the first driven wheel 164, and the other end of the rotating shaft 165 passes through the mounting seat body 123 along the first direction and extends out of the accommodating cavity to connect with the rotating mechanism 140. The first synchronous belt 163 is wound around the first driving wheel 162 and the first driven wheel 164, so that the first driving wheel 162 is connected to the first driven wheel 164. In this way, the rotating driving member 161 drives the first driving wheel 162 to rotate through the output shaft, and then drives the first driven wheel 164 to rotate through the first synchronous belt 163, and finally drives the rotating shaft 165 to rotate to drive the rotating mechanism 140 to rotate.

[0045] Furthermore, in some embodiments, a first detected unit 166 and a second detected unit 167 are further provided at the edge of the first driven wheel 164, and a first detection unit 168 and a second detection unit 169 are provided in the accommodating cavity. When the first detected unit 166 passes through the first detection unit 168, the first detection unit 168 can identify the first detected unit 166, and when the second detected unit 167 passes through the second detection unit 169, the second detection unit 169 can identify the second detected unit 167, thereby obtaining the rotation angle of the rotating mechanism 140, and then the working state of the rotating driving member 161 can be accurately controlled so that the rotating mechanism 140 is at different angles relative to the material picking device 200.

[0046] Specifically in one embodiment, the first detected unit 166 is a shielding piece with one end fixed to one end surface of the first driven wheel 164 and the other end protruding out of the edge of the first driven wheel 164, so the first detection unit 168 can obtain the number of rotations of the first driven wheel 164 by identifying the first detected unit 166. There are multiple second detected units 167, all of which are arranged at intervals along the circumference of the first driven wheel 164, and each second detected unit 167 is a notch formed on the edge of the first driven wheel 164. The second detection unit 169 can obtain the rotation angle of the first driven wheel 164 by identifying the second detected unit 167.

[0047] 1, 2 and 5, the rotating mechanism 140 is fixedly connected to one end of the rotating shaft 165 extending out of the accommodating cavity, so as to rotate synchronously with the rotating shaft 165. Specifically, the rotating mechanism 140 includes at least one rotating disk 141, which is generally a disk-shaped structure, and all the rotating disks 141 are arranged at intervals along the first direction, and a storage space 140a is formed on a side of each rotating disk 141 away from the mounting seat 120 to accommodate the storage unit 180.

[0048] Specifically, when the rotating mechanism 140 includes only one rotating disk 141 , one end of the rotating shaft 165 is fixedly connected to the center position of the rotating disk 141 , and a storage space 140a is formed on the side of the rotating disk 141 facing away from the mounting base 120 , and the storage unit 180 can be placed on the rotating disk 141 .

[0049] When the rotating mechanism 140 includes a plurality of rotating disks 141, all the rotating disks 141 are spaced and coaxially arranged along the first direction, one end of the rotating shaft 165 is fixedly connected to the lowest rotating disk 141, and two adjacent rotating disks 141 are fixedly connected by at least one connecting shaft 143, each connecting shaft 143 extends along the first direction, and opposite ends of the connecting shaft 143 are respectively fixedly connected to the two rotating disks 141. A storage space 140a is formed between two adjacent rotating disks 141, and a storage space 140a is also formed on the side of the uppermost rotating disk 141 facing away from the mounting seat 120.

[0050] It is understood that the number of rotating disks 141 in the rotating mechanism 140 is not limited, and can be set according to the number and type of reagent disks 2000 to meet different requirements. Specifically in one embodiment, the rotating mechanism 140 includes two rotating disks 141, the rotating disk 141 close to the mounting seat 120 is fixedly connected to the rotating shaft 165 of the driving mechanism 160, and the two rotating disks 141 are fixedly connected to each other through five connecting shafts 143, and a storage space 140a is formed between the two rotating disks 141 to accommodate the storage unit 180, and a storage space 140a is also formed on the side of the rotating disk 141 away from the mounting seat 120 facing away from the mounting seat 120 to accommodate the storage unit 180.

[0051] Further, in some embodiments, the rotating disk 141 is provided with at least one limiting groove 1412, and the storage unit 180 is limited in the limiting groove 1412, so as to prevent the storage unit 180 from moving and misaligning on the rotating disk 141. Specifically, the rotating disk 141 is provided with a plurality of limiting grooves 1412, and all the limiting grooves 1412 are arranged at intervals along the circumference of the rotating disk 141, so that a plurality of storage units 180 can be limited on each rotating disk 141. Specifically in one embodiment, each rotating disk 141 is provided with four limiting grooves 1412, so that four storage units 180 can be placed on each rotating disk 141. It can be understood that the number and arrangement of the limiting grooves 1412 on the rotating disk 141 are not limited thereto, and the number of limiting grooves 1412 on each rotating disk 141 can be the same or different.

[0052] As a preferred embodiment, as shown in combination with FIG. 5 and FIG. 6 , the groove wall of the limiting groove 1412 is provided with a first limiting portion 1412a, and the storage unit 180 is provided with a second limiting portion 1812. The first limiting portion 1412a and the second limiting portion 1812 can be interlocked with each other, so as to ensure that the storage unit 180 is placed on the rotating disk 141 at a correct angle and position, and the relative position of the storage unit 180 and the rotating disk 141 can be limited to prevent the storage unit 180 from moving on the rotating disk 141. Specifically in one embodiment, the groove bottom wall of the limiting groove 1412 is provided with two large and small circular holes as the first limiting portion 1412a, and the storage unit 180 is provided with two large and small cylindrical protrusions as the second limiting portion 1812. It can be understood that the specific structures of the first limiting portion 1412a and the second limiting portion 1812 are not limited thereto, and can be set as required.

[0053] Please refer to Figures 1, 2 and 6. Each storage unit 180 includes a bearing seat 181 and a plurality of limiting rods 183. The shape of the bearing seat 181 matches the shape of the limiting groove 1412 of the rotating disk 141 and is limited in the limiting groove 1412. All limiting rods 183 are inserted into the edge of the bearing seat 181 and arranged at intervals along the circumference of the bearing seat 181. The bearing seat 181 and the limiting rods 183 together form a sub-storage space 180a to accommodate the reagent disc 2000. Multiple reagent discs 2000 can be stacked and placed in the sub-storage space 180a along the first direction. Specifically in one embodiment, one storage unit 180 can store a maximum of 10 reagent discs 2000.

[0054] Specifically, in one embodiment, the limiting groove 1412 provided on the rotating disk 141 is roughly in the shape of an equilateral triangle, and one of the vertices of the limiting groove 1412 faces the central axis of the rotating disk 141, and the width of the limiting groove 1412 gradually increases from one end close to the central axis of the rotating disk 141 to one end close to the edge of the rotating disk 141. Correspondingly, the supporting seat 181 of the storage unit 180 is also roughly in the shape of an equilateral triangle, and the storage unit 180 includes three limiting rods 183, which are respectively inserted into the three vertices of the supporting seat 181.

[0055] The material taking device 200 is located at one side of the rotating mechanism 140 in the second direction. The material taking device 200 has a clamping mechanism 250. The clamping mechanism 250 is used to clamp the reagent disk 2000 in one of the storage spaces 140a.

[0056] Please refer to Figures 1, 7, 8 and 9, the material taking device 200 includes a mounting bracket 210 and a lifting mechanism 230. The mounting bracket 210 is arranged on one side of the material storage device 100 in the second direction, and the mounting bracket 210 extends longitudinally along the first direction. The lifting mechanism 230 is installed on the mounting bracket 210 and connected to the clamping mechanism 250, and the lifting mechanism 230 is used to drive the clamping mechanism 250 to lift and reciprocate in the first direction, so as to clamp the reagent disc 2000 located at different heights.

[0057] Specifically, the lifting mechanism 230 includes a lifting drive 231, a second driving wheel 232, a second driven wheel 233, a second synchronous belt 234 and a lifting seat 235. The lifting drive 231 is arranged at the bottom of the mounting bracket 210 in the first direction, and the output shaft of the lifting drive 231 extends along the third direction. The second driving wheel 232 is fixedly connected to the output shaft of the lifting drive 231, the second driven wheel 233 is rotatably arranged at the top of the mounting bracket 210 in the first direction around the third direction, and the second synchronous belt 234 is wound around the second driving wheel 232 and the second driven wheel 233. One end of the lifting seat 235 is fixedly connected to the second synchronous belt 234, and the other end of the lifting seat 235 is fixedly connected to the clamping mechanism 250.

[0058] In this way, the output shaft output torque of the lifting drive member 231 drives the second driving wheel 232 to rotate, and then drives the second driven wheel 233 to rotate synchronously through the second synchronous belt 234. The lifting seat 235 reciprocates along the first direction driven by the second synchronous belt 234, and finally drives the clamping mechanism 250 to reciprocate along the first direction.

[0059] The clamping mechanism 250 includes a clamping assembly 252 and a pick-and-place driving member 254, wherein the pick-and-place driving member 254 is installed on the lifting seat 235, wherein the output shaft of the pick-and-place driving member 254 extends along a first direction to connect the clamping assembly 252, and the pick-and-place driving member 254 is used to drive the clamping assembly 252 to rotate around the first direction to approach or move away from the rotating mechanism 140. When the rotating mechanism 140 rotates, the clamping assembly 252 moves away from the rotating mechanism 140 to avoid interfering with the rotation of the rotating mechanism 140. When the rotating mechanism 140 rotates to a preset position, the pick-and-place driving member 254 drives the clamping assembly 252 to approach the rotating mechanism 140 to take the reagent disk 2000. After taking the reagent disk 2000, the pick-and-place driving member 254 drives the clamping assembly 252 away from the rotating mechanism 140.

[0060] Furthermore, the clamping assembly 252 is also provided with a third detected unit 26, and the lifting seat 235 is installed with a third detection unit 258. When the third detected unit 26 passes through the third detection unit 258, the second detection unit 169 can identify the third detected unit 26 to obtain the rotation angle of the rotating mechanism 140, and then accurately control the working state of the pick-up and placement drive member 254.

[0061] The clamping assembly 252 includes an opening and closing drive unit 2521, a clamping unit 2523 and a guide rail 2525. The opening and closing drive unit 2521 is connected to the clamping unit 2523 and is used to drive the clamping unit 2523 to open and close. The guide rail 2525 cooperates with the clamping unit 2523 to guide the opening and closing of the clamping unit 2523.

[0062] Specifically, the clamping unit 2523 includes a first clamping jaw 2523a and a second clamping jaw 2523b, and the first clamping jaw 2523a and the second clamping jaw 2523b are spaced apart in the first direction. The opening and closing driving unit 2521 includes an opening and closing driving member 2521a, a first connecting rod, a second connecting rod and a third connecting rod. The output shaft of the opening and closing driving member 2521a extends along the first direction, the middle part of the first connecting rod is sleeved on the output shaft of the opening and closing driving member 2521a, one end of the second connecting rod and one end of the third connecting rod are rotatably connected to the opposite ends of the first connecting rod, the other end of the second connecting rod is rotatably connected to the first clamping jaw 2523a, and the other end of the third connecting rod is rotatably connected to the second clamping jaw 2523b. The guide rail 2525 extends along the first direction, and the first clamping jaw 2523a and the second clamping jaw 2523b are respectively limited to the two ends of the guide rail 2525 in the first direction.

[0063] In this way, the opening and closing driving member 2521a can drive the first connecting rod to rotate through the output shaft, and the rotation of the first connecting rod 2521b drives the second connecting rod and the third connecting rod to rotate, thereby driving the first clamping jaw 2523a and the second clamping jaw 2523b to move closer to or away from each other along the third direction under the limitation of the guide rail 2525, thereby clamping or releasing the reagent disk 2000.

[0064] In some embodiments, the clamping assembly 252 also includes an elastic connector 2526, which is formed by a structure that can undergo elastic deformation, such as a spring. The elastic connector 2526 is connected to the first clamp 2523a and the second clamp 2523b so that the two have a tendency to move closer to each other, so that the first clamp 2523a and the second clamp 2523b still maintain a certain distance after power is cut off, thereby preventing the reagent disk 2000 from falling from the clamping assembly 252.

[0065] Further in one embodiment, the clamping assembly 252 also includes a fourth detection unit 2527, one end of the fourth detection unit 2527 is installed on the first clamping jaw 2523a of the clamping unit 2523, and the other end of the fourth detection unit 2527 can extend into the sub-storage space 180a of the storage unit 180 to detect whether there is a reagent disk 2000 in the space.

[0066] The feeding principle of the above-mentioned feeding device 1000 is as follows:

[0067] The rotating mechanism 140 of the loading device rotates to a certain angle around the first direction under the drive of the driving mechanism 160, the clamping unit 2523 rotates toward the rotating mechanism 140 under the drive of the pick-and-place driving member 254, and the fourth detection unit 2527 extends into the sub-storage space 180a of one of the storage units 180. The fourth detection unit 2527 can detect whether there is a reagent disc 2000 in the sub-storage space 180a. After the fourth detection unit 2527 detects the reagent disc 2000, the clamping unit 2523 clamps the reagent disc 2000 under the drive of the opening and closing driving unit 2521, and then rotates away from the rotating mechanism 140 under the drive of the pick-and-place driving member 254.

[0068] During this process, the lifting mechanism 230 can drive the clamping unit 2523 to rise and fall in the first direction to pick up reagent disks 2000 of different heights. The first detection unit 168 and the second detection unit 169 control the rotation angle of the rotating mechanism 140 by detecting the positions of the first detected unit 166 and the second detected unit 167, so that different storage units 180 are within the picking range of the clamping unit 2523. The third detection unit 258 controls the rotation angle of the clamping unit 2523 by detecting the third detected unit 256.

[0069] The above-mentioned loading device 1000 can set the number of rotating disks 141 as needed, and multiple storage units 180 can be placed on each rotating disk 141. Different storage units 180 can store different types of reagent disks 2000. Multiple reagent disks 2000 can be stored in each storage unit 180. Therefore, the storage device of the loading device 1000 can store a large number of reagent disks 2000 of the same or different types, and the operator can load in batches by disassembling the storage unit 180 as a whole. Moreover, the loading device 1000 integrates the storage device 100 and the material removal device 200. The material removal device 200 is arranged on one side of the storage device 100 to take the reagent disk 2000 in the storage device 100, which has a higher loading efficiency.

[0070] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
